Measurements of the Nuclear Modification Factor for Jets in Pb+Pb Collisions at √sNN=2.76 TeV with the ATLAS Detector
Publisher DOI
Abstract
Measurements of inclusive jet production are performed in pp and Pb+Pb collisions at √sNN=2.76 TeV with the ATLAS detector at the LHC, corresponding to integrated luminosities of 4.0 pb⁻¹ and 0.14 nb⁻¹, respectively. The jets are identified with the anti-k t algorithm with R=0.4 , and the spectra are measured over the kinematic range of jet transverse momentum 32<p T <500 GeV, and absolute rapidity |y|<2.1 and as a function of collision centrality. The nuclear modification factor, R AA , is evaluated and jets are found to be suppressed by approximately a factor of two in central collisions compared to pp collisions. The R AA shows a slight increase with p T and no significant variation with rapidity.
